Answer:
h(x) = |x+10|---------------------------------------------------------
Explanation:
To shift the graph 10 units to the left, we replace x with x+10. What's really going on is that the xy axis shifts 10 units to the right (because x is now x+10; eg, x = 2 ---> x+10 = 2+10 = 12) so it appears that the graph is moving to the left. The general rule is h(x) = g(x+10).
So,
g(x) = |x|
g(x+10) = |x+10| ... every x has been replaced with x+10
h(x) = g(x+10)
h(x) = |x+10|
We can use a graphing tool like GeoGebra to visually confirm we have the right answer (see attached). Note how a point like (0,0) on the green graph moves to (-10,0) on the red graph.
Answer:
(6x+5)(4x−1)
Step-by-step explanation:
24x² + 14x - 5 Factor the expression
(6x+5)(4x−1) Double check the answer by FOILing
24x² - 6x + 20x - 5 Combine like terms
24x² + 14x - 5 This answer does work

Answer:
x = 2
Step-by-step explanation:
The mean is
3 + 7 + 8 + 10 + x
------------------------- = 6
5
Multiplying both sides by 5, we get:
3 + 7 + 8 + 10 + x = 30
Then 28 + x = 30, so that x must be 2
x = 2
Ratio:
Red : Total

Total of red and green marbles = 4 + 3 = 7
Blue marbles = 10 - 7 = 3
10 parts = 40 marbles
1 part = 40 ÷ 10 = 4
3 parts = 4 x 3 = 12
Answer: There are 12 blue marbles.
